' "1 Claim. i.te;2a;.;;

V 'I'heobject of 'my"'invention is to provide a door stop of simple, durable and'inexpensive constructioniwhich may be readily and easily applied to a door and readily and easily adjusted, so that when in operating position it will engage a floor with such accurate adjustment as to slightly flatten the flexible resilient riction wheel against the floor to thereby stop movement of the door in either direction.

A further object is to provide a doorstep of its operative or inoperative position, is conveniently accessible to an operators foot; whereby 7 it may be readily and easily moved from one position to the other, and when in inoperativev position it will be 'yieldingly held against acci- Figure 5 shows asectional view on the line 5-5 s of Figure 1.

My improved stop comprises a bracket of sim'- ple and inexpensive construction; It has a smooth straight upright portion 10 to be placed flat 7 against a door [1,. and two integral outwardly extended parallel arms l2.

-The bracket'is applied to a door for delicate vertical adjustment by means of a'm'etal clip 13 v having its ends shapedto engage a door and be 1 secured thereto by screws [3a and its central 10 this class in which thestop wheel, when in either fzszsrir hold the that easem nt-11m aoa'a em to ,f

By'this means the stop wheel yieldingly holds. the door against movement in one direction, to These relative pro- 7 the left as shown in Fig. 2. portions niustalso be such that when the stop wheel is in said position its inner surface will engage the bracket member lll'below a horizontal line'through the pivot and be held thereby against rotation in the direction required for moving the door toward-the: right, as shown in Fig. 2. 1 V

It is pivotallyconnected to the arm by a'bolt [6 extended through the arms and also through the wheel l5 at a point eccentric to thewheel.

'At the inner upper edge of the arms I2 I have formed inwardly extended projections ll shown in Fig. 5. It is important that the positions of these projections and th relative posithe wheel is turned to its inoperative position,

In this manner an unskilled operator may secure the device to" a door by the screws I3a, and'then' the-bracketv may be vertically adjusted by a so-calledfifit' and try procedure to determine the action of movedthe stop wheel by the floor so that it is In practice I have found that in many in:

stances it is desirable to holda door in partially opened position when it is subjected to pressure in both directions by the wind or otherwise, hence, it. is highly desirable that the door be held in both directions.

when a door is being opened and someshock" I have also-found that or jar is applied thereto, that the stop wheel is thereby moved to operative position, which is highly objectionable, and for this, purpose I have provided the projections l1 engaging the yielding sides of the stop wheel which have efiectively prevented such accidental movement. I have also demonstrated that it is very advantageous toreadily, quickly and easily move the stop wheel to any of its positions by a convenient-and easy operation of-tliejoperators foot, preventing the necessity of the operator steeping. over and us ing his hands.
